Device for securing cargo on the loading area

of a vehicle

The invention relates to a device for securing piece goods on the loading area of a vehicle or similar device in the form of a beam-like profile with connecting elements provided on it, in particular a - preferably extruded - hollow profile with hook-like connecting elements attached at both ends, on each of which a clamping web opposite the profile front edge is movable relative to the profile front edge.

EP 0 159 394 B1 discloses horizontal lashing rails in a truck body for securing items of clothing or similar elements. Based on this, DE 44 12 067 C by the applicant describes a pair of guide rails provided approximately horizontally on the vehicle side walls at a distance from the loading area, to which end connecting elements of a support profile running between them in the operating position are connected; this support profile is connected to a strand-like guide rod by a joint at a distance from one end of the profile and the guide rod is fixed in place at the other end by means of a further joint. This support profile can be folded around its joint and the guide rod around the further joint from an operating position into a rest position and can be attached to one of the guide rails by means of the end joint.

A hollow profile is also known which can be extended telescopically thanks to insertable intermediate tubes and has hooks at both ends as a so-called intermediate wall closure, between whose one hook leg and the adjacent profile front edge which is roughly parallel to it, a guide rail running transversely to the gap created here or a wall element of a truck body can be inserted. To generate a clamping force, the guide rail - which is hinged to a pull lever riveted to the rod profile - can be

A226DE8 - 2 \

The hook can be moved at a variable distance from the profile front edge which forms a clamping mouth with the clamping leg.

In view of this state of the art, the inventor has set himself the goal of improving the adaptation of the device described at the beginning to the conditions of the place of use as well as its manufacture and handling. In addition, the fit of the end clamping element on the vehicle-side connecting element is to be optimized.

The teaching of the independent claim leads to the solution of this problem; the subclaims cover advantageous further developments. In addition, all combinations of at least two of the features disclosed in the description, the drawing and/or the claims fall within the scope of the invention.

According to the invention, an insert body of a clamping element having the clamping web can be inserted into the beam-like profile or hollow profile of the device at the end and is movably mounted in the profile interior -- in the longitudinal axis of the hollow profile; according to a further feature of the invention, this clamping web can be the leg of an angle piece that is slidably guided in the clamping element. Thanks to these specifications, a one-piece hollow profile can be equipped with a clamping element at each end, which enables both the clamping and the length adjustment of the device.

It has proven to be advantageous to control the movement of the insert body by equipping it with a guide rail that is approximately parallel to the longitudinal axis of the hollow profile and in which a rod element that crosses the interior of the profile -- in particular a cross bolt fixed at both ends in the hollow profile -- is guided; the insert body is to be guided on the rod element or cross bolt of the hollow profile in the thrust direction running along the longitudinal axis of the hollow profile; the length of its thrust path is determined by the stop edges that delimit the guide rail on both sides.

A226DE8 ~2*l· \ *&iacgr;\,&Iacgr;'\ W J

The hollow profile should advantageously have a rectangular cross-section and a web-like wall of the insertion body should run approximately in the main cross-sectional axis of the insertion body, i.e. vertically or at right angles to that longitudinal axis; the web-like wall is provided with an at least partially polygonal opening, which offers the backdrop for the cross bolt through edges running transversely to the direction of thrust as a stop limit. The backdrop should preferably be limited by a side edge of the opening and an approximately parallel stop step of the ridge edge of the opening - or by two parallel opening edges. The design of the insertion body should advantageously be I-shaped; the two end flanges slide along the ceiling and floor wall of the hollow profile, and the aforementioned opening is made in the vertical web of the I-cross section.

The interaction of the parts described is facilitated by the fact that at least one section of a ridge flange of the insertion body delimits a guide gap for a ridge wall of the hollow profile associated with it and a web of the clamping element is located parallel to the ridge flange opposite. Furthermore, the guide gap should be closed by a cross wall attached to the insertion body at the end of the gap pointing against the direction of insertion. This cross wall, which is preferably one piece with the insertion body, limits its insertion path because it strikes the profile front edge of the hollow profile. The web, which is parallel to the ridge flange of the insertion body, projects beyond the cross wall on both sides in the direction of insertion.

The invention also includes a further guide gap of the clamping element, which is intended for a leg or bearing web of the angle piece that can be moved therein, the other leg of which forms the clamping web. This guide gap is at least

• VJ * · · · «19»· 4 *

A226DE8 - δ'&igr;- 1 ·: :.':■:

The gap end facing the slot is open; it is intended to accommodate the bearing web of the angle piece that is brought into this slot.

According to another feature of the invention, the clamping web, which can be moved back and forth with respect to the approximately parallel profile front edge, should have an elastic counter-clamping surface on the end of the insert body facing it, preferably at least one insert made of hard rubber or similar material seated in a receiving space provided on the transverse wall of the insert body. The inner surface of the clamping web facing the latter can also be coated with the elastic material.

In a preferred embodiment, a section of at least one bolt protrudes from the counter-clamping surface and can engage in an opening of a holding profile inserted between the clamping partners - for example in the form of a so-called airline profile described in DE 297 06 258 U by the applicant. By closing the closure according to the invention, the bolt is held in its preferred position.

In order to control the clamping process, a pivoting lever that can be moved in the direction of the main cross-sectional axis mentioned is connected to at least one bearing formation of the clamping element - on the side of the guide gap(s) facing away from the insert body - by means of a pivoting bolt; this is used to adjust the variable distance between the clamping web on the one hand and its counter-clamping surface on the other.

According to a further advantageous provision, bearing lugs protrude from the clamping element, in which a pivot pin is seated that passes through the bearing end of the pivot lever. A lever arm is also hinged to the pivot lever at a distance from its articulation point, which is connected to the angle piece by means of a base end, advantageously at its knee. The lever arm can be used to adjust the

A22 6DE8 , - 5. -;

Tension force must interact with a force accumulator, in particular be enclosed by a coil spring.

The bearing end of the swivel lever is preferably designed like a fork, and the lever arm is arranged between the two "prongs" of this bearing end. In the clamping position, the lever arm running between the angle piece and the swivel lever should be approximately parallel to the swivel lever and the clamping web should be opposite the counter surface at a short clamping distance.

When the swivel lever is swung out of the clamping position, the lever arm swings through the bearing end of the swivel lever or, in the absence of a fork-shaped end of the swivel lever, it moves past the swivel lever in the case of parallel external bearing.

The adjustment range in the subject matter of the invention is therefore not in the area of the hollow profile but directly in the connecting element attached at the end, which is only connected to the hollow profile by means of the described cross bolt -- and can be moved within it to a limited extent.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing, which shows in

The loading area 10 of a vehicle not shown in detail is flanked by side walls 12 of a box body 14, the box front wall of which is designated here with 16 and the roof with 18.

A226DE8 - 7. -J

At a distance q from the loading surface 10, this is spanned by a so-called intermediate wall closure 20, which makes it possible to secure loads 11 arranged on the loading surface 10 for transport without requiring changes to the box structure 14. This intermediate wall closure 20 has a clamping element 26 partially inserted into the profile space 24 at both ends of a box-shaped hollow profile 22 -- extruded from an aluminum alloy, for example -- with which the intermediate wall closure 20 can be releasably secured to a stationary profile 30 of the box structure 14 -- or otherwise.

The profile can, for example, be a so-called airline profile 30 _a according to Fig. 2 with a width b of 100 mm and a height i of 25 mm with an undercut longitudinal groove 34 running in the longitudinal center of its surface 32 and round recesses 36 made in this at center distances η of diameter d of approximately 20 mm -- shorter than the center distance η.

The hollow profile 22 of the partition wall closure 20 offers, in the area of its ends, a section of its profile space 24 for receiving an insert body 28 of the clamping element 26 that can be inserted in the insertion direction x; this insert body 28 of length e is -- in accordance with the cross-sectional image indicated by arrow Q in Fig. 3 -- of I-shaped cross-section, and the cross-sectionally rectangular hollow profile 22, whose cross-sectional main axis is designated by B, nestles against it in a leading manner. The vertical web 40 of the insert body 28 has a substantially rectangular opening 42, the ridge edge 43 of which forms a vertical stop step 44 at approximately half the opening length f. This delimits, together with the right-hand side edge 46 of the opening 42, which runs at a horizontal distance fi and is shown in Fig. 3, 4, a sliding path or a guide for a cross bolt 38 which is fixed at both ends in the hollow profile 22 and which guides the insertion body 28. The latter can be removed from the hollow profile 22 after the cross bolt 38 has been unscrewed.

A226DE8 - 8, -: 1 * J &idigr; . :

A transverse wall 28 is firmly connected to the cross-sectionally I-shaped insert body 28 at its end pointing against the insertion direction x. Outside the hollow profile 22, two receiving chambers 52 for cuboid-shaped hard rubber inserts 58 can be seen on this transverse wall 48, separated by an intermediate wall 49 which can be seen approximately in the longitudinal axis A of the hollow profile 22 and flanked by side walls 50 -- open towards the rear.

Fig. 4 in particular shows that above the ridge flange 41 of the insertion body 28 and at a distance from it, a web 54 of the clamping element 26 runs, which is formed on the transverse wall 48 and is simultaneously the ridge wall for the upper receiving chamber 52. On the other hand, this web 54 delimits, together with the ridge flange 41, a guide gap 56 for the ridge wall 23 of the hollow profile 22.

The different positions of the clamping element 26 are particularly clear in Fig. 3; a vertical leg of an angle piece 62 of the clamping element 26, which is opposite the hard rubber inserts 58 mentioned and acts as a clamping web 60, determines on the left in Fig. 3 a wide gap 61 in the open position of width t to the surface of the hard rubber inserts 58, possibly several times the size of the gap width ti in the clamping position sketched at the right end of the partition wall closure 20.

The angle piece 62 consists essentially of the clamping web 60 and a second leg which forms a bearing web 64; this is displaceable above the web 54 in a further guide gap 57 of the clamping element 26. According to Fig. 4, the upper guide gap 57 is overlapped at the top by a further web wall 55 which -- like the web 54 parallel to it -- is integral with the side walls 50 of the receiving chamber 52.

A22 6DE8 - 9. '-· [ · · J, *:

Bearing tabs 66 for a pivot pin 68 of a pivot lever 70 protrude above the web wall 55, the fork-like bearing end 71 of which is penetrated by a further bearing pin 72 at a distance ζ (Fig. 3, 5) from the pivot pin 68. This is used to link a further lever or lever arm 74 to the pivot lever 70, one end of which is connected by an axle pin 76 to a bearing 63 on the elbow of the angle piece 62.

If the pivot lever 70 is guided in the opening direction y -- Fig. 3, 5 --, the bearing web 64 of the angle piece 62 moves within its guide gap 57, and thus the clamping web 60 also moves away from the adjacent hard rubber inserts 58 serving as a counter-clamping surface, as well as from the corresponding profile front edge 21 of the hollow profile 22. The two crossing levers 70, 74 thus create a type of "X" on the bearing bolt 72 in side view.

When the pivot lever 70 is pivoted against the opening direction y -- right end of Fig. 3 -- the angle piece 62 is displaced towards the profile while reducing the distance ti; the bearing bolt 72 is guided around the pivot bolt 68 and the two levers 70, 74 are aligned, i.e. in the clamping position according to Fig. 4, the pivot lever 70 and lever arm 74 lie parallel to the hollow profile 22. In Fig. 4, an elastic layer on the inner surface of the clamping web 60 is also indicated at 59.

Fig. 5 shows the interaction of the clamping element 26 with an end rail 30b of a vehicle-side profile wall 78, similar to an airline profile rail, on whose upper edge it is fixed with a pair of parallel retaining flanks 79. One of the above-described round recesses 36 of the undercut longitudinal groove 34 here receives the free end of a snap bolt 80 which protrudes from the surface of the upper hard rubber insert 58.

The clamping element 26 _a of Fig. 6, 7 with a total length ei and a total height h has a rectangular opening 42 _a in the vertical web 40 of its insertion body 28 for the cross bolt 38 (not shown here); the opening width £2 acts here according to the distance U ₁ of the connection step 44 from the opening side edge 46 in the embodiment of Fig. 3 to 5.

The web wall spanning the upper guide gap 57 is replaced here by aligned horizontal legs 55 _a of two cross-sectionally angled flank walls 82; these delimit a longitudinal slot 84 _f in which a neck part 65 of the bearing web 64 of angle piece 62 is guided.

Above those horizontal legs 55 _a of the flank walls 82, in Fig. 7, between the parallel bearing brackets 66 which are formed to project slightly laterally, sections 71 _{a on} both sides of the fork-shaped bearing end 71 of the pivot lever 70 are indicated, which are connected to the bearing brackets 66 by two pivot bolts 68. The axial length of the gap between these sections 71 _a on the one hand and the distance k of the free lever arm end from its bearing point 72 are coordinated with one another; this lever arm end passes through the gap during the clamping process. The clamping force can be adjusted here by a helical spring 86 which surrounds the lever arm 7 4 .
